Stainless Steel 904L Ferrule Fittings
What is 904L stainless steel used for?
This grade, alloyed with 23-28% chromium, 4-5% nickel, and molybdenum, enjoys favour with many industrial applications. Stainless steel 904L ferrule fittings display excellent resistance to corrosion and pitting and have a low carbon content that protects against intergranular corrosion.
The core applications of this superaustenitic stainless steel are in chemical processing plants for producing phosphate-based fertilisers. 904L ferrule fittings are straightforward to install and deliver leak-tight performance in petrochemicals, bleaching equipment for paper production, and gas desulfurisation.
SS 904L instrumentation fittings use a double-ferrule arrangement for a firm and secure mechanical grip between tubing. The basic structure includes a body, a nut, and the ferrule.

What are the properties of Stainless Steel 904L Ferrule Fittings?
Ferrule fittings are standard piping components to build leak-proof and well-aligned connections. WNR 1.4539 tube fittings usually get manufactured in sizes of 1/8 to 2 inches for pressure ratings up to 10,000 psi.
904L stainless steel double ferrule fittings can withstand seawater, sulfuric acid, and chlorides without experiencing damage or loss in strength. They are highly corrosion resistant, with an average PREN of 36.7.
Here are other properties that make them sought after by many industries:
- Can handle severe temperatures up to 450°C
- High tensile and yield strength of 490 and 220 MPa
- Retain mechanical properties at elevated temperatures
- Ideal for changing thermal conditions in heat exchangers and condensers
- Good weldability using standard techniques

How does the tensile strength of Stainless Steel 904L Ferrule Fittings vary with temperature?
Buyers must consider environmental factors while choosing ASTM B649 UNS N08904 ferrule fittings. These components boast excellent mechanical strength even in elevated conditions.
As a rule of thumb, the tensile strength increases when the temperature reduces. It comes down when the temperature increases since the grain size and the dislocation density rise.
On the other hand, the ductility of SS 904L tube fittings decreases with decreasing temperature.
